A 24-year-old girl was referred with a massive thyroglossal duct cyst (TGDC) and an intra-cystic papillary thyroid cancer (PTC). The impressive clinical photographs, striking radiological images and histology slides are presented.She presented eight and half months post partum with a 10 cm midline neck lump of 4 years duration. She was asymptomatic and was on levothyroxine for Hashimoto’s thyroiditis.Clinically, there was a cy...

Introduction: Regimens for pre-operative α and β-blockade for patients with secretory phaeochromocytomas/paragangliomas vary widely between centres. The worldwide lack of availability of intravenous phenoxybenzamine (Goldshield) has removed a useful tool in the management of phaeochromocytoma crisis and has necessitated a change in our institution’s routine pre-operative strategy. We compare pre, peri and post-operative surrogate measures of blockade in a cohort...

Background: Pituitary macroadenomas are an uncommon cause of Cushing’s disease. They present with a higher cortisol burden, are more aggressive and harder to cure and manage than microadenomas.Aims: To review the demographics, clinical features, biochemistry, radiology and required treatment modalities of a single-centre case series of corticotroph macroadenomas.Methods: Retrospective analysis and review of the case records of...

A 37-year-old woman, 30 weeks pregnant, presented with palpitations and abdominal cramps. Ultrasound demonstrated a supra-renal abnormality and MRI showed a 10 cm heterogeneous left adrenal mass. For five years she had experienced episodes of palpitations, shaking, sweating and chest tightness. She was investigated by a neurologist and diagnosed with temporal lobe epilepsy. During pregnancy the frequency of episodes increased. Lamotrigine was started, but at each dose increase...

Primary aldosteronism (PA) is an important cause of hypertension which confers significant cardiometabolic risk. In approximately half of cases, the cause is a surgically resectable unilateral aldosterone-producing adrenal adenoma, making PA the most common potentially curable form of hypertension. Despite this, long-term data on surgical outcomes that could be used to guide discussions with patients are sparse. Here, we report on clinical outcomes several years post-adrenalec...

Medullary thyroid carcinoma (MTC) is a rare malignancy which has often metastasised at time of diagnosis. Surgical resection represents the only prospect for cure. However, debulking neck surgery may be beneficial in advanced cases. Prophylactic surgery is increasingly undertaken in asymptomatic patients with known mutations in the RET oncogene. The aim was to describe the outcome following initial surgical treatment for MTC at our institution. We performed a retrospe...
